You should note something very important about the cryptocurrencies;
What really matters is from the angle you are sighting it from, crypto currency is not a ponzi scheme rather than you putting your funds in a wrong project and with the wrong people at the wrong time. Therefore, make proper researched about any project you want to venture into mostly the newly birth project with low ratings or similarly. Now talking about withdrawal fees; today we have many chain with low gas fee which you could only spend $0.1 or lesser. so it's advisable you switched to such network.
